How would you calculate the number of nanometers in 8.1 cm

Answers

Answer 1

A: 8.1 • 10^7 nanometers

Because 1cm = 1 • 10^7 nm
So 8.1cm • (1 • 10^7 nm) = 8.1.10^7

Why is polarity a key connection between the structure of a molecule and its properties?

Answers

The intermolecular force of the molecule is determined by the polarity of the molecule and hence the physical properties of a molecule are affected. As polar molecules would have stronger intermolecular forces than non-polar molecules, they have higher boiling points, freezing points and surface tension. Further, a polar molecule would retain an assymmetrical structure while non-polar molecules will be symmetrical. Hence polarity determines structure of molecules and its properties.

Polarity is crucial because it affects a molecule's solubility, boiling and melting points, and intermolecular interactions. Polar molecules dissolve well in polar solvents, have higher boiling and melting points due to strong dipole-dipole interactions, and can form hydrogen bonds, influencing their behavior and properties in various environments.

1. Solubility: Polar molecules tend to dissolve well in polar solvents (like water) because of the attraction between the partial charges on the molecules and the solvent. Non-polar molecules dissolve better in non-polar solvents (like oils).

2. Boiling and Melting Points: Polar molecules generally have higher boiling and melting points compared to non-polar molecules of similar size because the dipole-dipole interactions (forces between the positive end of one polar molecule and the negative end of another) are stronger than the van der Waals forces present in non-polar molecules.

3. Intermolecular Interactions: Polarity determines the type of intermolecular forces a molecule can participate in, such as hydrogen bonding (a strong type of dipole-dipole interaction found in molecules with N-H, O-H, or F-H bonds), which significantly affects the physical properties and reactivity of the molecule.

Sodium metal reacts with water to form aqueous sodium hydroxide and hydrogen gas. which equation below best describes the balanced equation for this reaction?

Answers

Let's start by writing the basic equation:
Na(s) + H2O(l) ↔ NaOH(aq) + H2 (g)

Now balance:

2Na(s) + 2H2O(l) ↔ 2NaOH(aq) + H2 (g)

The balanced equation between sodium metal and water to form aqueous sodium hydroxide and hydrogen gas is: 2Na(s) + 2H2O(l) ↔ 2NaOH(aq) + H2 (g)

According to this question, sodium metal reacts with water to form m aqueous sodium hydroxide and hydrogen gas as follows: Na(s) + H2O(l) ↔ NaOH(aq) + H2(g)

However, this reaction is not balanced because the number of atoms of each element on both sides of the equation are not the same.

To balance the equation, we make use of coefficients, which are numbers placed in front of the elements. The balanced equation is as follows:

2Na(s) + 2H2O(l) ↔ 2NaOH(aq) + H2 (g)
